An exhaust gas recirculation device is provided. The device recirculates, from an exhaust system to an intake system, a part of exhaust gas from a plurality of cylinders of a multi-cylinder engine as EGR gas. The device includes a single EGR pipe extending from the exhaust system toward the intake system, an EGR manifold branching from a downstream end portion of the EGR pipe toward each cylinder, and an EGR valve for adjusting an EGR gas amount. The EGR manifold has one or more common EGR passages having a single pipe portion and branched pipe portions, and one or more independent EGR passages. Each shape of the common and independent EGR passages is set so that a communicating path in the EGR manifold communicating an arbitrary cylinder with a cylinder where combustion is performed subsequently thereto has the same volume for any cylinder combination having the adjacent combustion order.

A method of ensuring the safety of exhaust of a water heater includes the following steps: A. start the blower and detect a rotational speed of a motor thereof; B. determine a first range based on the detected rotational speed; C. start the blower and detect the rotational speed of the motor when the water heater is restarted again; D. keep supplying gas to the burner for combustion when the rotational speed detected in step C is within the first range. During operation, a second range is determined by detecting the rotational speed of the motor after an outlet water temperature reaches a corresponding constant temperature range; the rotational speed is continuously detected, and the gas supply is stopped if the detected rotational speed is out of the second range. Thereby, the result of the method would be more accurate regardless of the actual installed status of the exhaust pipe.

( Work stress )

( MtY stress )

( MtE stress )

( Mom stress )

I'm thinking of getting therapy just to have someone to talk to about all the stress. The good thing (honest, I see it as a good thing) is that most of the stress is basically external to me -- my days are generally easy and pleasant, and everyone who's not me may be melting down, but all my stress is in the way of a contact low, as it were. Other than being in a sandwich-generation holding pattern (when will the next phase of my life begin? no one knows), things are pretty good. I'm making more money than I ever have, I love my work, I get lots of downtime to read and hang out with James and mom, and my health is better than it's been in years. So yeah, if the universe could just leave my loved ones in peace, that'd be great.

We conducted a large-scale survey covering 58 countries and over 100,000 respondents between late March and early April 2020 to study beliefs and attitudes towards citizens’ and governments’ responses to the COVID-19 pandemic. Most respondents reacted strongly to the crisis: they report engaging in social distancing and hygiene behaviors, and believe that strong policy measures, such as shop closures and curfews, are necessary. They also believe that their government and their country’s citizens are not doing enough and underestimate the degree to which others in their country support strong behavioral and policy responses to the pandemic. The perception of a weak government and public response is associated with higher levels of worries and depression. Using both cross-country panel data and an event-study, we additionally show that strong government reactions correct misperceptions, and reduce worries and depression. Our findings highlight that policy-makers not only need to consider how their decisions affect the spread of COVID-19, but also how such choices influence the mental health of their population.

Abstract, references and article information

A single bout of exercise enhances insulin action in the exercised muscle. However, not all human studies find that this translates into increased whole-body insulin action, suggesting that insulin action in rested muscle or other organs may be decreased by exercise. To investigate this, eight healthy men underwent a euglycemic-hyperinsulinemic clamp on 2 separate days: one day with prior one-legged knee-extensor exercise to local exhaustion (~2.5 h) and another day without exercise. Whole-body glucose disposal was ~18% lower on the exercise day as compared with the resting day due to decreased (~37%) insulin-stimulated glucose uptake in the nonexercised muscle. Insulin signaling at the level of Akt2 was impaired in the nonexercised muscle on the exercise day, suggesting that decreased insulin action in nonexercised muscle may reduce GLUT4 translocation in response to insulin. Thus, the effect of a single bout of exercise on whole-body insulin action depends on the balance between local effects increasing and systemic effects decreasing insulin action. Physiologically, this mechanism may serve to direct glucose into the muscles in need of glycogen replenishment. For insulin-treated patients, this complex relationship may explain the difficulties in predicting the adequate insulin dose for maintaining glucose homeostasis following physical activity.

Abstract:
Given a sequence ${X_{n}}_{ngeq 1}$ of exchangeable Bernoulli random variables, the celebrated de Finetti representation theorem states that $frac{1}{n}sum_{i=1}^{n}X_{i}stackrel{a.s.}{longrightarrow }Y$ for a suitable random variable $Y:Omega ightarrow [0,1]$ satisfying $mathsf{P}[X_{1}=x_{1},dots ,X_{n}=x_{n}|Y]=Y^{sum_{i=1}^{n}x_{i}}(1-Y)^{n-sum_{i=1}^{n}x_{i}}$. In this paper, we study the rate of convergence in law of $frac{1}{n}sum_{i=1}^{n}X_{i}$ to $Y$ under the Kolmogorov distance. After showing that a rate of the type of $1/n^{alpha }$ can be obtained for any index $alpha in (0,1]$, we find a sufficient condition on the distribution of $Y$ for the achievement of the optimal rate of convergence, that is $1/n$. Besides extending and strengthening recent results under the weaker Wasserstein distance, our main result weakens the regularity hypotheses on $Y$ in the context of the Hausdorff moment problem.

Expressing yourself and trying to read others’ faces in a grid of video feeds is a taxing task

Most people read a book only once—satisfied they’ve learned the story or the information it communicates, they don’t feel the need to read it again. Some ardent fans might return to a cherished book again and again, but the majority of readers eagerly move on to something new. So why is the Bible different? Why does God’s Word demand our constant attention?
